public static String CURRENT_TAG = TAG_HOME;
// toolbar titles respected to selected nav menu item

To add the Tablayout with NavigationDrawer :
1.create a new File “TabFragment.java” to inflate & code TabLayout and viewPager elements.
2.For viewPager to display content it requires a Adapter . use a FragmentPagerAdapter which is used to inflate tab specific fragments.
3.The FragmentPagerAdapter overrides three main methods :
a) getCount() : It returns the total number of tabs to be bind with the view pager.
b) getItem(int position) : It returns the tab-specific fragment wrt to its position.
c) getPageTitle(int position)` : It returns name of the title according to the position
4.At the end , attach your ViewPager with the TabLayout with the setupWithViewPager(viewPager) method of the TabLayout .
Here is a detail implementation: https://androidbelieve.com/navigation-drawer-with-swipe-tabs-using-design-support-library/
Hope it helps.
As u are using toolbar you can use:
@Override
public boolean onNavigationItemSelected(MenuItem menuItem) {
//Checking if the item is in checked state or not, if not make it in checked state
if (menuItem.isChecked()) menuItem.setChecked(false);
else menuItem.setChecked(true);
//Closing drawer on item click
drawerLayout.closeDrawers();
//Check to see which item was being clicked and perform appropriate action
switch (menuItem.getItemId()) {
case R.id.first:
toolbar.setTitle("First Item");
return true;
case R.id.second:
toolbar.setTitle("Second Item");
return true;
}
}
to set title..during click on fragments
